DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

Referring now to the drawings, and more particularly to FIGS. 1-4, shown therein is a perspective view of an apparatus 10 for conditioning and strengthening an individual. The apparatus 10 includes a housing 14 and a plurality of handles 16. The housing 14 defines a fluid retaining chamber 20 (FIG. 3) and is provided with an opening which is in fluid communication with the fluid retaining chamber 20 so that fluid can be introduced into or withdrawn from the fluid retaining chamber 20. A removable cover 24 in the form of a plug or cap, for example, is provided for sealing the opening. A valve stem and the like may also be used to seal the opening 22.

The housing 14 has an upper side 30, a lower side 32 opposite the first side 30, a first end 34, a second end 36 opposite the first end 34, a first side 38, and a second side 40 opposite the first side 38. In one embodiment, the first and second sides 38 and 40 have a curvilinear shape while the upper side 30 and the lower side 32 are substantially planar. In such a configuration, the housing 14 and the fluid retaining chamber 20 have a substantially hourglass or dumbbell profile viewed from the upper side and the lower side (FIG. 3).

The housing 14 further comprises at least two openings 42 extending through the housing 14 from the upper side 30 to the lower side 32 and equally spaced on opposite sides of a center line 44 of the housing 14. The openings 42a and 42b provide access to the handles 16a and 16b from the upper side 30 and the lower side 32 of the housing 14. Each of the openings 42a and 42b is traversed by one of the handles 16a and 16b, respectively. In one embodiment, the handles 16a and 16b are axially aligned with a longitudinal axis 46 of the housing 14. The openings 42a and 42b, and thus the handles 16a and 16b, are spaced so that an individual can grasp the handles 16 and lift the apparatus 10. Lifting the apparatus 10, with or without fluid, allows for conditioning and strengthening of the arms, upper torso, and legs of an individual.

The housing 14 further has notches 48a and 48b formed on the first end 34 and the second end 36, respectively, extending from the upper side 30 to the lower side 32. Furthermore, a handle 16c and traverses the notch 48a, and a handle 16d traverses the notch 48b. The handles 16c and 16d extend parallel to one another and are oriented in a direction normal to the longitudinal axis 46 of the housing 14.

The housing 14 and the handles 16 may be fabricated from any suitable material such as canvas, rubber, or any polymeric material. By way of example, the housing 14 and the handles 16 may be constructed from a resilient material having an elastomeric memory which allows the housing 14 and the handles 16 to return to their original shape after being lifted.

The fluid retaining chamber 20 is adapted to receive fluid. The fluid may be any substance that flows and takes the shape of the fluid retaining chamber 20, such as a liquid, a gas, sand and the like. The fluid is disposed in the fluid chamber 20 in an amount sufficient to provide the housing 14 with a predetermined or desired weight.

The size of the housing 14 and the capacity of the fluid retaining chamber 20 can vary widely so as to provide an apparatus suitable for use by individuals of various size and strength. That is, for children the housing 14 can be small in size and may have an empty fluid retaining chamber 20. In contrast, the housing 14 for men would be larger and the fluid retaining chamber 20 may contain a large volume of fluid to increase the weight of the apparatus 10.

The apparatus 10 may also include a frame (not shown) embedded within the housing 14 for increasing the structural integrity of the housing 14 and the plurality of handles 16. Any suitable construction may be used so that the frame supports and provides structural integrity to the housing 14 and the handles 16. The frame may be constructed into any desired shape such as an oval, ellipse, or square. However, the frame is desirably provided with a configuration corresponding to the peripheral configuration of the housing 14.

FIGS. 5-7 illustrate another embodiment of an apparatus 10a for conditioning and strengthening an individual. The apparatus 10a includes a housing 14a and a plurality of handles 50. The housing 14a is similar to the housing 14 in that the housing 14a is shown to have a generally hourglass or dumbbell shape. The handles 50a and 50b traverse a first pair of openings 52a and 52b formed through the housing 14a. The openings 52a and 52b provide access to the handles 50a and 50b from the upper surface 30 and the lower surface 32 of the housing 14a. The housing 14a includes a second pair of openings 54a and 54b positioned outside of the openings 50a and 50b and traversed by handles 52c and 52d. As illustrated, the handles 52c and 52d are oriented similarly to the orientation of the handles 16a and 16b described above in reference to the apparatus 10. However, the handles 52a and 52b are oriented in a direction normal to the longitudinal axis 46 of the housing 14a.

The apparatus 10a is further provided with a pair of handles 56a and 56b formed at the first and second ends 34 and 36 of the housing 14a in a manner similar to that described above in reference to the apparatus 10.

FIGS. 8-9 illustrate another embodiment of an apparatus 10b for conditioning and strengthening an individual. The apparatus 10b is similar to the apparatus 10a except as described below. The apparatus 10b includes a housing 14b and a plurality of handles 60. The housing 14b is similar to the housings 14 and 14a in that the housing 14b is shown to have a generally hourglass or dumbbell shape. The handles 60a and 60b traverse a first pair of openings 62a and 62b formed in the upper side 38 of the housing 14b. Unlike the openings 52a and 52b described above, the openings 62a and 62b only extend partially through the housing 14b as best illustrated in FIG. 9. The housing 14b includes a second pair of openings 64a and 64b positioned outside of the openings 62a and 62b and traversed by handles 60c and 60d. Again, the openings 64a and 64b only extend partially through the housing 14b As illustrated, the handles 60a-60d are oriented similarly to the orientation of the handles 50a-50d described above in reference to the apparatus 10.

The apparatus 10b is further provided with a pair of handles 66 formed at the first and second ends 34 and 36 of the housing 14b in a manner similar to that described above in reference to the apparatus 10.

In use, water may be added to the apparatus. Less water equals less weight, more water equals more weight. One gallon of water weighs 8.3 pounds. In one version, the apparatus 10 has the capacity of 26 gallons which provides a maximum weight of approximately 250 pounds. The addition or removal of water allows the weight to be adjusted according to the size and ability of the participant and the activity.

The apparatus 10 can be used as an alternative for barbell work. Furthermore, the apparatus 10 can be used for a dynamic warm-up and finish work apparatus. Because of the water inertia, lower weights can be used to activate stabilizing muscles and engage the core in a wide variety of movements. All pressing and squatting movements, and even standing still and just maintaining balance are enhanced.

Athletes can capture the inertia of water as they move with the apparatus 10. Athletes will work their core and stabilizing muscles by fighting the water as it moves around inside housing. By combining movements with the apparatus 10, athletes will work more areas more thoroughly than with dumbbells or barbells, and usually at a lesser weight.

From the above description it is clear that the present invention is well adapted to carry out the objectives and to attain the advantages mentioned herein as well as those inherent in the invention. While presently preferred embodiments of the invention have been described for purposes of this disclosure, it will be understood that numerous changes may be made which will readily suggest themselves to those skilled in the art and which are accomplished within the spirit of the invention.
